What is SASE?
Secure Access Service Edge is a cloud-based IT model that packages software-defined networking and network security functions together and delivers them from a single service provider. It provides stable connectivity and protection everywhere so that people can work anywhere.
SASE gives you greater control and visibility over users, traffic, and data accessing your network. Networks built with SASE are flexible and scalable and able to connect your employees and offices across any location and on any device.
SASE Components
Combing software-defined wide area networking (SD-WAN) capabilities with network security functions, SASE is a single cloud platform. It helps you enable your employees to authenticate and securely connect to internal resources from anywhere, giving you greater control over the traffic and data that enters and leaves your internal network.
Four core security components:
Cloud Access Security Broker (CASB) performs several security functions for cloud-hosted services, including revealing shadow IT, securing access control to sensitive data and data loss prevention (DLP), and ensuring data privacy compliance and regulations. It secures access to SaaS applications such as Office 365.
Zero Trust Network Access (ZTNA) platforms lock down internal resources and requires real-time verification of every user and device to every protected application. It replaces traditional remote access solutions where the VPN are terminated in your on-premises datacentre.
Firewall-as-a-Service (FWaaS) are a cloud-based next-generation firewall that includes URL filtering, intrusion prevention, and uniform policy management across all network traffic to protect your cloud-based platforms, infrastructure, and applications.
Secure web gateways (SWG) prevent data breaches by filtering unwanted content from web traffic, blocking unauthorised user behaviour, and applying your organisation’s security policies. SWGs can be deployed anywhere, making them ideal for securing remote workforces.
Depending on the software solution and your requirements, the core components can include additional security services such as web application and API protection (WAAP), remote browser isolation, or Wi-Fi hotspot protection.
